ClassSpacesLogo Design Contest

#1 I'm looking for something more distinctive / unique, if possible. I know this isn't very specific feedback; I'm hoping this will get easier as additional concepts come in for comparison.

#2 The puzzle piece with 3-d perspective is more interesting - thanks. I'd be interested in additional concepts that imply education and/or collaboration in some way (not sure exactly what that looks like). Color contrast also helps; many of the classroom teachers we work with are drawn to bright, bold colors.

#5 I like the simplicity of this design, and that it conveys people working together and the notion of a "place." Implying "CS" is a nice touch, also. I'd be interested to see the text in blue & green rather than black & green

Dear gfalcon,
Thank's for your appreciation.
It would be nice if you give your feedback in designer's private comment.
It just click on the picture and then you give any request that you need.
About that will be ready soon.
Thank's.

Crafthink,

My apologies if I've gone against convention by posting comments in public - this is my first time using logotournament. My intent was both to convey ideas for revisions (which I'll do privately here forward), but also to try to help focus in on what aspects of the design resonate for me. Not being a designer myself, it is sometimes difficult to say in advance "here is what I like" - but it is easier to point to an example that is good and identify what is good about it.

Thanks!

OK. No problem. I could understand about the first CH in here/LT.
This post for general comment that anyone can give comments about everything in your logo contest.
Good luck ! Thank you.
